The northern terrestrial net ecosystem carbon balance (NECB) is contingent on inputs from vegetation gross primary productivity (GPP) to offset the ecosystem respiration (R_eco) of carbon dioxide (CO₂) and methane (CH₄) emissions, but an effective framework to monitor the regional Arctic NECB is lacking. We modified a terrestrial carbon flux (TCF) model developed for satellite remote sensing applications to evaluate wetland CO₂ and CH₄ fluxes over pan-Arctic eddy covariance (EC) flux tower sites. The TCF model estimates GPP, CO₂ and CH₄ emissions using in situ or remote sensing and …

Wilderness Management In National Parks And Wildlife Refuges, Sandra B. Zellmer

Faculty Law Review Articles

This Article provides a wilderness scorecard of sorts for the two "dominant use" land management agencies-the National Park Service (NPS) and the United States Fish and Wildlife Service (FWS). Given that both agencies operate under a similar conservation oriented mandate, one night assume that the imposition of a wilderness mandate would be closely aligned with their organic missions. However, NPS and FWS have both, at times, been surprisingly hostile toward wilderness within their systems. In NPS's case, this is likely because of a concern that wilderness might disrupt visitor use and rein in its management discretion over park activities and …

Consequences Of A Refuge For The Predator-Prey Dynamics Of A Wolf-Elk System In Banff National Park, Alberta, Canada, Joshua F. Goldberg, Mark Hebblewhite, Jonathan M. Bardsley

Wildlife Biology Faculty Publications

Refugia can affect predator-prey dynamics via movements between refuge and non-refuge areas. We examine the influence of a refuge on population dynamics in a large mammal predator-prey system. Wolves (Canis lupus) have recolonized much of their former range in North America, and as a result, ungulate prey have exploited refugia to reduce predation risk with unknown impacts on wolf-prey dynamics. We examined the influence of a refuge on elk (Cervus elaphus) and wolf population dynamics in Banff National Park. Elk occupy the Banff townsite with little predation, whereas elk in the adjoining Bow Valley experience higher wolf predation. The Banff …

Public Land & Resources Law Review

The United States District Court for the District of Columbia found that the BLM and Forest Service did not act arbitrarily and capriciously when they maintained and extended a boundary fence and decided not to expand a wild horse and burro range. The court also held the BLM used reasoned decision making when it determined a target horse and burro population in a herd management plan. Additionally, a National Environmental Policy Act claim was defeated under the “capable of repetition yet evading review” exception to the mootness doctrine.

Snowshoe Hares Display Limited Phenotypic Plasticity To Mismatch In Seasonal Camouflage, Marketa Zimova, L. Scott Mills, Paul M. Lukacs, Michael S. Mitchell

Ecosystem and Conservation Sciences Faculty Publications

As duration of snow cover decreases owing to climate change, species undergoing seasonal colour moults can become colour mismatched with their background. The immediate adaptive solution to this mismatch is phenotypic plasticity, either in phenology of seasonal colour moults or in behaviours that reduce mismatch or its consequences. We observed nearly 200 snowshoe hares across a wide range of snow conditions and two study sites in Montana, USA, and found minimal plasticity in response to mismatch between coat colour and background. We found that moult phenology varied between study sites, likely due to differences in photoperiod and climate, but was …

Insights Into The Development And Evolution Of Exaggerated Traits Using De Novo Transcriptomes Of Two Species Of Horned Scarab Beetles, Ian A. Warren, J. Cristobal Vera, Annika Johns, Robert Zinna, James H. Marden, Douglas J. Emlen, Ian Dworkin, Laura C. Lavine

Biological Sciences Faculty Publications

Scarab beetles exhibit an astonishing variety of rigid exo-skeletal outgrowths, known as ‘‘horns’’. These traits are often sexually dimorphic and vary dramatically across species in size, shape, location, and allometry with body size. In many species, the horn exhibits disproportionate growth resulting in an exaggerated allometric relationship with body size, as compared to other traits, such as wings, that grow proportionately with body size. Depending on the species, the smallest males either do not produce a horn at all, or they produce a disproportionately small horn for their body size. While the diversity of horn shapes and their behavioural ecology …

Hilar Mossy Cells Provide The First Glutamatergic Synapses To Adult-Born Dentate Granule Cells, Jessica H. Chancey, David J. Poulsen, Jacques I. Wadiche, Linda Overstreet-Wadiche

Biomedical and Pharmaceutical Sciences Faculty Publications

Adult-generated granule cells (GCs) in the dentate gyrus must establish synapses with preexisting neurons to participate in network activity. To determine the source of early glutamatergic synapses on newborn GCs in adult mice, we examined synaptic currents at the developmental stage when NMDA receptor-mediated silent synapses are first established. We show that hilar mossy cells provide initial glutamatergic synapses as well as disynaptic GABAergic input to adult-generated dentate GCs.

A Conceptual Framework For Clutch-Size Evolution In Songbirds, Thomas E. Martin

Wildlife Biology Faculty Publications

Causes of evolved differences in clutch size among songbird species remain debated. I propose a new conceptual framework that integrates aspects of traditional life-history theory while including novel elements to explain evolution of clutch size among songbirds. I review evidence that selection by nest predation on length of time that offspring develop in the nest creates a gradient in offspring characteristics at nest leaving (fledging), including flight mobility, spatial dispersion, and self-feeding rate. I postulate that this gradient has consequences for offspring mortality rates and parental energy expenditure per offspring. These consequences then determine how reproductive effort is partitioned among …

Biological Sciences Faculty Publications

Engaging large numbers of undergraduates in authentic scientific discovery is desirable but difficult to achieve. We have developed a general model in which faculty and teaching assistants from diverse academic institutions are trained to teach a research course for first-year undergraduate students focused on bacteriophage discovery and genomics. The course is situated within a broader scientific context aimed at understanding viral diversity, such that faculty and students are collaborators with established researchers in the field. The Howard Hughes Medical Institute (HHMI) Science Education Alliance Phage Hunters Advancing Genomics and Evolutionary Science (SEA-PHAGES) course has been widely implemented and has been …

Invasive Plant Erodes Local Song Diversity In A Migratory Passerine, Yvette K. Ortega, Aubree Benson, Erick Greene

Biological Sciences Faculty Publications

Exotic plant invasions threaten ecosystems globally, but we still know little about the specific consequences for animals. Invasive plants can alter the quality of breeding habitat for songbirds, thereby impacting important demographic traits such as dispersal, philopatry, and age structure. These demographic effects may in turn alter song-learning conditions to affect song structure and diversity. We studied Chipping Sparrows (Spizella passerina) breeding in six savannas that were either dominated by native vegetation or invaded by spotted knapweed (Centaurea stoebe), an exotic forb known to diminish food resources and reproductive success. Here, we report that the prevalence of older birds was …

National Climate Indicators System Report, National Climate Assessment And Development Advisory Committee

Numerical Terradynamic Simulation Group Publications

The National Climate Assessment (NCA), a component of the U.S. Global Change Research Program (USGCRP), is designed to produce periodic scientific assessments of the vulnerability of important sectors in the U.S. to climate change and variability, and to report on response strategies for responding to and coping with change. An important feature of the NCA is to develop climate-relevant information for use by a wide variety of stakeholders in the public and private sectors and in the scientific community. The development of a national system of indicators is an essential feature of such information, and provides a foundation for assessing …

Developmental Link Between Sex And Nutrition; Doublesex Regulates Sex-Specific Mandible Growth Via Juvenile Hormone Signaling In Stag Beetles, Hiroki Gotoh, Hitoshi Miyakawa, Asano Ishikawa, Yuki Ishikawa, Yasuhiro Sugime, Douglas J. Emlen, Laura C. Lavine, Toru Miura

Biological Sciences Faculty Publications

Sexual dimorphisms in trait expression are widespread among animals and are especially pronounced in ornaments and weapons of sexual selection, which can attain exaggerated sizes. Expression of exaggerated traits is usually male-specific and nutrition sensitive. Consequently, the developmental mechanisms generating sexually dimorphic growth and nutritiondependent phenotypic plasticity are each likely to regulate the expression of extreme structures. Yet we know little about how either of these mechanisms work, much less how they might interact with each other. We investigated the developmental mechanisms of sex-specific mandible growth in the stag beetle Cyclommatus metallifer, focusing on doublesex gene function and its …

Phenoxybenzamine Is Neuroprotective In A Rat Model Of Severe Traumatic Brain Injury, Thomas Rau, Aakriti Kothiwal, Annela Rova, Joseph F. Rhoderick, David J. Poulsen

Biomedical and Pharmaceutical Sciences Faculty Publications

Phenoxybenzamine (PBZ) is an FDA approved α-1 adrenergic receptor antagonist that is currently used to treat symptoms of pheochromocytoma. However, it has not been studied as a neuroprotective agent for traumatic brain injury (TBI). While screening neuroprotective candidates, we found that phenoxybenzamine reduced neuronal death in rat hippocampal slice cultures following exposure to oxygen glucose deprivation (OGD). Using this system, we found that phenoxybenzamine reduced neuronal death over a broad dose range (0.1 μM–1 mM) and provided efficacy when delivered up to 16 h post-OGD. We further tested phenoxybenzamine in the rat lateral fluid percussion model of TBI. When administered …
